Description

Cyclopentanecarbonitrile, 2-(Acetyloxy)-1-(2-Propenyl)-, (1S,2R)- (9Ci) is a high-purity, stereochemically defined chiral intermediate of significant value in advanced organic synthesis. This compound is engineered to provide a critical, enantiomerically pure building block for the development of complex active pharmaceutical ingredients (APIs) and fine chemicals. It is essential for research and production chemists in the pharmaceutical, agrochemical, and specialty chemical industries who require reliable, high-quality chiral synthons to streamline complex synthetic routes.

Application

• Pharmaceutical Intermediate: A key chiral building block for the synthesis of novel therapeutic agents, particularly in the development of central nervous system (CNS) and cardiovascular drugs.
• Agrochemical Synthesis: Used in the research and production of enantiomerically pure pesticides and herbicides, where specific stereochemistry is crucial for bioactivity.
• Asymmetric Catalysis Research: Serves as a valuable substrate or ligand precursor in the development and testing of new asymmetric catalytic reactions.
• Fine Chemical Production: Employed in the multi-step synthesis of complex fragrance molecules, flavors, and other high-value specialty chemicals requiring precise stereocontrol.
• Academic & R&D Laboratories: A critical reagent for methodological studies in organic chemistry, particularly in stereoselective synthesis and natural product total synthesis projects.
